MOP FAIL AND WRINGER.

Application filed April 1, 1925.

To all whom it may concern:

Be it known that 1, WILLIAM M. Clams-rorrinn, a citizen of the United States, residing at Tonawanda, in the county of Erie and State of New York, have lnvented certain new and useful Improvements in Mop Pails and lVringers, of which the following is a specification.

This invention relates to the class of mop pails and attached wringers.

The prin'iary object of this invention is the provision, in a manner as hereinafter set forth, of a mop pail and wringer of an improved structure wherein pressure may be brought to bear upon a mop, to express the water therefrom as it is drawn from the pail, through the downward movement of the bail which serves as pail handle.

Another object of the invention is the pro vision, in a manner as hereinafter set forth, of a mop pail and wringer having an improved means for moving a squeeze roller toward a stationary roller, to squeeze a mop and express liquid therefrom when the same is withdrawn from the pail between the.

said rollers.

Another object of the invention 1s the pro vision, in a manner as hereinafter set forth, in a mop pail and wringer, of improyed means for retracting a wringer mechanism after the same has been released from contact with a mop which is being wrung.

A further and final object of the invention is the provision, in a manner as hereinafter set forth, of a mop pail and wringer, of strong and durable construction, unique design, positive and efficient in action, and so constructed that the catching or tearing of a mop used in connection therewith is avoided.

The invention will be best understood from the consideration of the following detailed description taken in connection with the accompanying drawing forming a part of this specification, with the understanding however, that the invention is not confined to any strict conformity with the showing of the drawing but may be changed and modified so long as such changes and modi 'fications mark no material departure from the salient features of the invention as expressed in the appended claims.

In thedrawingz V I Figure l is a horizontal transverse section through the pail embodying this inven- Serial No. 19,985.

ti n, looking toward the top thereof and at the underside of the mechanism comprising the wringer structure. This section is taken upon line 11 of Figure 2.

Figure 2 is a vertical longitudinalsectional View taken upon the line 22 of Figure 1.

Referring now to the drawing in detail wherein like numerals of reference indicate corresponding parts throughout the several views, there is indicated generally by the numeral 1 a pail having the inclined sides 22 and the bottom 3. It will be noted that the pail is at its top, substantially rectangu lar, having two long sides and one straight short side, the other short side being arcuate in contour. The purpose for this construction will become apparent as the description proceeds.

Extending ,tl'iroughout the length of the short side of the pail along the top edge thereof and continuing along and for substantially half the length of each long side of the pail, is a downwardly and inwardly directed skirtor drip guard comprising the cross portions at and the side portions 5. It will be noted from reference to Figure 2 that the portion 4 is of greater length or extends further into the pail than the side portion 5 and that the lower edgeof the side portiono has a slight inclination from the rear to the point 6 where the degree of inclination is increased as shown to bring this edge down to meet the lower edge of the portion 4-.

Extending transversely of the pail, beneaththe lower edge of the portion at of the drip skirt, is a shaft 7 carrying thereon a roller member 8. It will be noted that the roller member 8 has a portion thereof extending beyond the lower edge of the portion 4 of the skirt, whereas the major portion of the roller is below the skirt proper.

Extending transversely of the pail body at the upper central portion thereof is a stationary shaft 9 having upon one end outside of the pail body the securing nut 10. Upon the shaft 9 there is mounted for reoiprocable swinging movement a platform indicated by the numeral 11, and this platform has depending from each side edge and adjacent the back thereof, the flanges 12 in each of which there is formed the longitudinally extending slot 13, through which slot the shaft 9 extends to pivotally support the platform.

When the platform is in the raised position indicated in Figure 2, it will be seen that the side edges thereof abut against the lower edge of the portions 5 of the skirt, and the front edge of the platform upon extreme forward movement thereof reaches the point 6 of the side portions 5 of the shirt.

The rear edge of the platform 11 is downturned as at 14 and there is secured to the central portion of the inner face of this downturned portion, by means of the clamp device 15, an arcuate spring 16 having two parallel arms upon each side of the fixed point 15 which arms are connected at their ends toform the loop 17 which overlies the rear of the shaft 9, and through their tension upon the shaft normally tend to draw the platform backwardly upon the shaft.

Depending from each side of the platform 11 adjacent the forward edge thereof, is a downwardly and forwardly extending car 18, and extending between and connecting these ears is a shaft 19 upon which is mount ed a solid roller 20. When the platform 11 is moved forwardly upon its support 9, the

roller 20 comes to a point in close proximity to the roller 8 as shown in Figure 2.

The platform 11 has a central depressed bearing surface 21 extending transversely thereof midway between the sides as shown in Figure 1, and the purpose of this depressed portion will become apparent as the description proceeds.

Secured upon the under side of the platform 11 one upon each side of the raised central portion 21 is a circular housing 22 having the securing ears by means of which the housing is attached to the platform, and thesehousings are enclosed at the end directed toward the front of the platform and open at the rear. lVithin each of the housings there is placed a spiral spring 24, and positioned within each of these springs 24 is a plunger member 25 hav ng the annular flange or head 26, the underside of which bears against the spring 24 in which the plunger is placed. At the rear of each of the plungers 25 there is a screw member 27 one end of the same. of which is secured in the rear end of the housing 22, and extended through the rear end of the plunger 25 and having the head thereof secured within the plunger thus preventing the spring 24 from forcing the plunger outwardly beyond a certain point. It will be noted that this screw 27 has the shank thereof threaded in the end of the housing 22 and it is therefore adjustable to increase or decrease the tension of the spring 24 by drawing'the lunger in or letting it be pressed outward y.

Formed through each long side of the pail beneath the shaft 9 and toward the front of the 'pail is a collared aperture 28 through which the inturned ends 29 of the bail or handle 80 extend. After passing through the apertures 28, these inturned ends 29 have the portions 31 extended at an oblique angle with respect to the sides of the bail and terminated and secured in the tubular plunger contacting member 32 as shown in Figure 1. At the central portion of this plunger contacting member 32 is a collar 33 about which a roller member 34 is positioned to revolve. This roller member 34 as will be seen upon reference to Figure 1 is indirect alignment with the depressed portion 21 of the platform and when the device is in operation to wring a mop, contacts with and rides upon the depressed portion as shown in Figure 2.

Upon reference to Figure 2 it will be seen, upon referring to the dotted line position of the bail 30, that the oblique portion 31 when the bail is in upright or vertical position extends toward the rear of the pail and downwardly. \Vhen the bail is in this position the spring 16 will have drawn the platform 11 back upon the shaft 9 and the platform will be in the downwardly inclined or dropped position as indicated in dotted lines in this figure. When the bail. is swung forwardly the roller 34 will rise and contact with the rear of the portion 21 and roll therealong raising the platform to substantially horizontal position. Further depression of the bail 30 will. bring the tubular portion in contact with the plunger 25 and the platform and roller 20 will thus be forced forwardly against the tension of the spring 16 to grip a mop, indicated in dotted lines by the numeral 35, between the rollers 8 and 20. Additional strain or pressure put upon the bail will be taken up by the springs 24, and the proper spring tension will be maintained bythe roller 20 against the mop 35 thus allowing the same to be easily with drawn from between the rollers but at the same time properly expressing the water absorbed thereby.

Upon one side of the pail 1 there is positioned the stop member 36 which prevents v the bail 30 from being swung over towards the roar of the pail, thus when it is raised it will be held in vertical position shown in dotted lines in Figure '2.

Extending downwardly and inwardly from the short side of the pail and upon the inner face of each long side thereof, below the roller 8, is the guide member 36, which projects inwardly across the ends of the rollers 8 and 20, and thus serves to prevent the mop 35 from working beyond the ends of the rollers and thereby becoming entangled around the supporting shafts thereof.

Formed circumferentially aboutthe body 1 of the pail is a corrugation 37 to indicate the proper height to which water should be placed in the pail. When filled to the point ndicated the pail will then contain sufficient fie welghtto' prevent tippinglor upsetting of the-same when, pressure 1S applied to the ball bail having the ends thereof extended through the sides of said pa-il', and a roller carrying; meanssuspended in said I pail for pivotal and. reciprocating movement, the

ends of said pail cooperating witlr-said roller carrying means to shift said'means to cause he roller-carried thereby to ,move toward the stationary: roller upon depression of the bail.'.:-
